POLISHED-ROD ROTOR.

Application iiled June 29, 1926. Serial No. 119,329.

VThis invention relates to polished rod rotors for use in rotating the movable parts such as the polished rod, the sucker rod and the cups or plunger of a well pump.

More specifically the invention forming the subject of this application is in the nature of an improved actuating means for a rotor, through the medium of which, the rotor may be expeditiously adjusted for usein le connection with pumping beams of various widths. i

A further and equally7 important object of the invention is to provide a novel form of actuatoi` by means of which the necessary l motion is efficiently transmitted from the attaching'base of the rotor to the clutch mechanism of the rotor. Y

Another object of the invention is to provide a pump accessory of the character specified which is of highly simplified construction, cheap to manufacture and one which is adaptable for use under a variety of conditions.

Other objects and advantages will be apparent during` the course of the following description.

In the accompanying drawing forming a part of this application and in which like numerals are employed to designate like 30 parts throughout the same.

Figure 1 is a perspective of the improved pumping accessory applied;

Figure 2 is a group perspective 0f the accessory detached;

Figure 3 is a vertical sectional View illustrating the manner in which the base plate of the accessory may be adjusted for use Vin connection with beams of various widths;

Figure 4 is a horizontal sectional view through the actuator and the arm thereof;

Figure 5 is a sidek elevation illustrating a slight modification of-the invention.

In the drawing numeral 5 designates the beam of a ack known in the industry as an V Oklahoma jack and which as suggested in Figure 1 consists of a pair of spaced -parallel channel beams having their flanges extended outwardly. This, however, forms no part of this invention and is referred to merely to provide a basis forthe: statement that the beams are not always of the same width or of the same cross sectional formation and the invention forming the subject matter of this application is intended to provide r simple mechanical means whereby the base plate of a rotor may be economically produced for application to beams of various widths.

In carrying out the invention, I provide a base plate consisting of main sections 6 and 7 the outer portions of which are provided with downwardly and inwardly projecting ribs or flanges 8 and 9, respectively, to extend about and engage the laterally projecting flanges of the'beam, all of which is clearlyshown in Figure 1. y

The inner portion of the section 6 of the base plate is offset so that the same may overlap and rest upon the section 7 in the manner shown in Figure 1 and is formed with an elongated slot 11, the wall of which is raised as shown at 12 to strengthen and reinforce the inner portion of the section 6. In addition tov strengthening and reinforcing the inner portion of the section 6, the raised rib 12 provides a generous bearing surface for the upwardly extendingboss 14 of the section 7.

Inspection of Figures V1 and 2 will clearly show that the boss 14 is adapted to be extended through the slot 11 and the laterally projecting Voppositely located ears 16 positioned above the shoulder 12. This'holds the parts loosely together preparatory to their application to the beam and therefore greatly simplifies' the installation of the rotor. y

When the base has bee-n properly positioned on the beam the set screw 2O threaded through one end of the section (iis tightened and by reason of the engagement of the set screw with the boss 14 the section 7 is moved inwardly so that both the attaching ribs 8 and .9 ywill be firmly engaged with the adjacent flanges of the beam. Figures 1 and 3 clearly illustrate that what might be said to be the outer 'side of the boss 14 is verti- *callyy grooved for the reception of the inner portion of the set screwV 20. f By making the opening 11 elongated the base is capable of a wide variety of adjustment and may be applied to any beam within very generous limits. This makes the manufacture of a number' of sizes of base plates for use in con.- nection with different size beams unnecessary.

Figures 2 and 3 illustrate that the outer side of the section 7, or more specifically that side of the section 7 opposite the slot y24 is laterally extended to define a shelf or track upon which the'adjacent portion of the-section 6 rests -to overcome any tendency of one of the sections and adapted to receive the actuator of a rotor.

2. A base plate for polished rod rotors comprising a pair of sections having beam engaging means, one oit the sections overlapping the other section, the section which is overlapped being provided with a boss extending through the overlapping portion of one of the sections and adapted to receive the actuator of a rotor, said boss being slotted for the passage of the shank of an actuator therethrough.

An attaching base for polished rod rotors comprising a pair of sections having beam engaging means, one of which is formed with a slot, the other section being provided with a boss detachably extended through said slot.

L An attaching base for polished rod rotors comprising a pair of sections having beam engaging means, one oi? which is formed with a slot, the other section being provided with a boss detachably extended through said slot, and means carried by said boss to hold the sections together preparatory to the application ot the same to a beam.

5. An attaching base for polished rod rotors comprising a pair of sections having beam engaging means, one ot' which is formed with a slot, the other section being provided with a boss detachably extended through said slot, and means carried by said boss to hold the sections together preparatory to the application of the same to a beam, said boss and the associated sections of the same being provided with a passage for the shank of an actuator.

6. An attaching base for polished rod rotors comprising a pair of sections having beam engaging means, one of which is 'formed with a slot, the other section being provided with a. boss detachably extended through said slot, and means carried by said boss to hold the sections together preparatory to the application of the same to a beam` said boss and the associated sections oit the same being provided with a passage for the shank of an actuator, and means whereby said sections may be moved into locking engagement with a beam.

7. An adjustable attaching base tor a polished rod actuator comprising a pair or" sections, one of which is provided with an inner portion overlapping the other section and having an elongated slot, a boss extending upwardly from one of the sections and extending through said slot, said boss being provided with ears adapted to be positioned above the slotted inner portion of one of the sections, a set screw carried by the slotted inner portion of one of said sections and adapted for engagement with said boss whereby the sections may be forcedy into locking engagement with a beam.

8. An adjustable attaching base for a polished rod actuatorl comprising a pairof sections, one ot which is provided with an inner portion overlapping the other section and having an elongated slot, a boss extending upwardly trom one ot the sections and extending through said slot, said boss being provided with ears adapted to be positioned above the slotted inner portion of one of the sections, a set screw carried by the slotted inner portion of one of said sections and adapted for engagement with said boss whereby the sections may be forced into locking engagement with a beam, said boss being adapted to rotatably receive an actuator and having means to limit upward movement of the actuator.

9. The combination of a base having a pair of sections, one of which has an opening, an actuator rotatably extending through said opening and adapted to rest upon a pumping beam, the wall of said opening being provided with means to limit upward movement of the actuator.

10. The combination of an-Vactuator having a head provided with a sockethaving one end open and an offset web at one side ot' said opening, and an Varm having a terminal portion received in said opening and having arcuate ribs, one ot which is engaged with said web, and a latch connecting said head and said arm and engaged by one ot said ribs.

1l. The combination of a pair of members, one of which has a socket opened at one end, the other member being provided with a terminal portion received in said socket and adapted to partake of a limited rocking movement therein, a latch detach-- ably holding said terminal portion in the socket, and means to limit lateral movement ot one member with respect to the other.

l2. The combination o'f a pair of members, one of which has a head provided with an opening and a web, the other member being provided with a terminal portion received in said opening and having laterally projecting ribs, one of which is engaged with said web, and a latch connect-ing the members and having an offset portion receiving the other rib.
